TENDER-TANK VALVE.

Specification of Letters Patent.

Patented Nov. 7, 1916.

Application filed April 26, 1916. Serial No. 93,588.

Tank Valves, of which improvement the fol-' lowing is a specification.

My invention relates to valves for controlling the supply of water fromthe tank of a locomotive tender to the injector connections on thelocomotive, and its object is to provide an appliance of such type whichwill be desirably applicable in connection with the water bottom tendertanks which are now in general service, and which will obviate thenecessity of perforating the upper sheets of the water bottom andextending the operating shaft through the coal space of the tender, andwill also enable either the valve member proper or the strainer, orboth, to be removed and replaced whenever desired, without involving thedelay and waste of draining the water from the tank.

The improvement claimed is hereinafter fully set forth.

In the accompanying drawings: Figure 1 is a plan or top view of anappliance illustrating an embodiment of my invention; Fig. 2, a verticallongitudinal central section through the same; Fig. 3, an end view, inelevation, as seen from the right; and, Fig. 4;, a vertical transversesection, on the line a; as of Fig. 2.

In the practice of my invention, referring descriptively to the specificembodiment thereof which is herein exemplified, I provide a valvecasing, 1, which is preferably, as shown, an integral casting, and whichis divided by horizontal and vertical partition walls into a waterreceiving chamber, 1, which is located at its top; a valve chamber, l",and a strainer or discharge chamber, 1". The valve and strainer ordischarge chambers are disposed with their axes in a common verticalplane below the water re ceiving chamber, and are of substantiallycircular cross section, the valve chamber varying therefrom by beingflattened at its top by the partition which divides it from the waterreceiving chamber. The axis of the strainer or discharge chamber islocated below that of the valve chamber, thereby caus- 7 the object ofthis construction being to give the freest possible access of water tothe strainer ordischarge chamber for a determined volume thereof whichwill enable the entn'e casing to be made of as small dimensions aspossible. An inlet opening, which may be, as shown, of the full diameterof the water. receiving chamber, is formed in the top thereof, saidopening being surrounded by a flange, 1, through which the casing isconnected to the bottom of the tender tank, around an opening therein,and a delivery nozzle, 1", is formed on the bottom of the wall of thestrainer or discharge chamber, for the attachment of a pipe or hosesection leading to the injector on the locomotive.

Communication between the valve and strainer or discharge chambers iscontrolled by a main or service valve, 2, of the lift or puppet type,which is fitted between guides, 1 in the valve chamber, and is adaptedto close on a seat, 1 surrounding an opening in the partition wallbetween the valve and strainer or discharge chambers. The valve, 2, isfitted detachably between collars on a valve stem, 3, having an externalthread, 3, which engages a corresponding internal thread on a nut, 4,fixed in a head, 4:, which closes an opening in the outer end of thevalve chamber, and is secured detachably to the casing, 1, by studs, 4The valve stem passes through a stufiing boX, 4, on the head, a, andcarries, on its outer end, a hand wheel, 3*, by which it may be rotated,to move the valve, 2, to and from its seat as desired.

A cylindrical strainer, 6, is fitted in the strainer or dischargechamber, being interposed between the seat of the service valve, 2, andthe discharge nozzle, 1 said strainer being insertible and removablethrough an end opening in the casing which is closed by a removablehead, 1 secured in position by studs, 1, and nuts.

The water receiving chamber communicates with the valve chamber througha. normally open passage, 1 formed in the partition wall between the twochambers, said passage being controlled by a supplemental shut-offvalve, 5, connected to and operable by a stem, 5, which passes through astuffing box, 1, on the wall of the water receiving chamber, on theopposite side of the easing from the valve stem 3 and is coupled to Y ahandle section, 5 lVhen the shut-off valve is moved ofi its seat for theoperation of the appliance in service, the handle section drops bygravity, and prevents the accidental or undesired closure of theshut-off valve.

It will be observed that all the parts of the appliance are readilyaccessible, and that either the service valve or the strainer, or

both, can be readily removed for cleaning or repair, Whenever desired.By closing the supplemental shut-0E valve, this can be done Withoutdrawing off the water from the tender tank. I

I claim as my invention and desire to secure by Letters Patent:

1. A valve casing provided at its top with flanges for attaching it tothe underside of a tank floor, the upper part of the casing form ing aninlet chamber, a horizontally sliding valve in said chamber to controlthe egress therefrom, a valve chamber located below one side of andnormally communicating with said inlet chamber, a horizontally slidingvalve in said valve chamber to control the egress therefrom, a strainerchamber located below the other side of said inlet chamand horizontalcylindrical valve and strainer chambers below, the partitions betweenthe inlet and valve chambers and between the valve and strainer chambershaving openings surrounded by valve seats, and the strainer chamberhaving a discharge opening in its bottom, horizontally movable valves insaid inlet and valve chambers, re-

spectively, to close said openings, and means 7 for actuating saidvalves projecting through opposite sides of the casing.
